Paint can with an internal molded label

ABSTRACT

The present invention provides an improved structure of a paint can with internal molded label. The paint can includes a plastic can body in a circular shape; a plastic bottom wall, integrally formed on the bottom of the plastic can body; and a plastic bottom frame, integrally formed on the bottom of the plastic can body and plastic bottom wall. There is a cover, covering the top of the plastic can body, and an internal molded label, integrated on the outside of the plastic can body through internal molding. The bottom edge of the internal molded label extends to the plastic bottom frame. In this way, an advancement of practicability is achieved in that the internal molded label of the paint can becomes smoother, and the quality of finished products is further improved.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a type of paint can, and moreparticularly to an innovative paint can with an internal molded label.

2. Description of Related Art Including Information Disclosed Under 37CFR 1.97 and 37 CFR 1.98

Traditional paint cans are usually made of metallic material. The paintcans commonly seen in the market to contain emulsion paint or cementpaint are mostly made of plastic materials.

The outer surface of such plastic paint cans is usually covered with alabel for advertising and marking. However, as the outer surface area ofa paint can becomes larger and larger, such label-covering work isinefficient. It is more and more difficult to meet the quality standardspursued in terms of accuracy and durability.

Based on this, the industry developed a structure to form a labelintegrally onto the plastic material during injection molding of thepaint can. However, during actual application of such prior art, it isfound that the edge of the label structure may easily become wrinkleddue to squeezing in the process of injection molding of the plasticstructure, causing insufficient flatness of the label surface andconsequently a high rates of irregular finished paint cans. Hence, suchprior art technology is really not an ideal product expected by theindustry.

Thus, to overcome the aforementioned problems of the prior art, it wouldbe an advancement in the art to provide an improved structure that cansignificantly improve efficacy.

Therefore, the inventor has provided the present invention ofpracticability after deliberate design and evaluation based on years ofexperience in the production, development and design of relatedproducts.

BRIEF SUMMARY OF THE INVENTION

The present invention achieves improved efficacy.

Through an innovative and unique invention, a bottom edge of theinternal molded label of the paint can extends to a plastic bottomframe. The present invention improves upon the prior art because thesurface of the internal molded label of the paint can becomes smoother,and the quality of finished products is further improved.

Although the invention has been explained in relation to its preferredembodiment, it is to be understood that many other possiblemodifications and variations can be made without departing from thespirit and scope of the invention as hereinafter claimed.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be morereadily understood upon a thoughtful deliberation of the followingdetailed description of a preferred embodiment of the present inventionwith reference to the accompanying drawings.

FIGS. 1, 2, and 3 are preferred embodiments of the improved structure ofthe paint can with internal molded label. Such embodiments are presentedfor descriptive purposes with respect to the claims.

The paint can A comprises a plastic can body 10 in a circular shapewhich defines a can space 11, while the top of the plastic can body 10is formed with a circular protrusion 12 extending to the outside.

There is a plastic bottom wall 20, which is integrally formed on thebottom of the plastic can body 10.

The paint can also includes a plastic bottom frame 30, which isintegrally formed on the bottom of the plastic can body 10 and plasticbottom wall 20. The plastic bottom frame 30 and plastic can body 10 areconnected smoothly through the circular wall extending downward.

A cover 40 of the paint can A covers the top of the plastic can body 10.

An internal molded label 50 is integrated on the outside of the plasticcan body 10 through internal molding. The bottom edge 51 of the internalmolded label 50 extends to the plastic bottom frame 30.

The internal molded label 50 can be integrated on the whole area or partof the area on the outside of the plastic can body 10.

As shown in FIGS. 2 and 3, the bottom edge 51 of the internal moldedlabel 50 can be extended to a position above the bottom of the plasticbottom frame 30 with a height separation.

The above-described structures form the present invention. The bottomedge 51 of the internal molded label 50 extends to the plastic bottomframe 30. During injection molding of the paint can A (refer to FIG. 3),when the internal molded label 50 is first placed in the injection moldbefore injection molding of the plastic part, the injection point isusually located at a position corresponding to the plastic bottom wall20. When the plastic material W1 flows from the plastic bottom wall 20to the plastic can body 10 and the plastic bottom frame 30, the flow ofthe plastic material W1 will be divided into two, one flowing upward tothe plastic can body 10 (as marked W2 in the figure), and the otherflowing downward to the plastic bottom frame 30 (as marked W3 in thefigure). During injection of the plastic material, as the bottom edge 51of the internal molded label 50 extends to the plastic bottom frame 30,the plastic material W3 flowing downward to the plastic bottom frame 30will simultaneously smooth in the downward direction the bottom edge 51of the internal molded label 50.

Therein, as shown in FIG. 4, the bottom edge 51 of the internal moldedlabel 50 can also extend to the bottom of the plastic bottom frame 30.

1. A paint can with an internal molded label, said paint can comprising:a plastic can body in a circular shape, defining a can space and havinga top formed with a circular protrusion extending outward; a plasticbottom wall, being integrally formed on a bottom of said plastic canbody; a plastic bottom frame, being integrally formed on the bottom ofthe plastic can body and plastic bottom wall, and being shaped as acircular wall extending downside, through which, the plastic bottomframe and plastic can body are connected smoothly; a cover engageable tothe top of the plastic can body; and an internal molded label, beingintegrated on an outside of the plastic can body through internalmolding and having a bottom edge of the internal molded label extendedto the plastic bottom frame.
 2. The paint can defined in claim 1,wherein the internal molded label can be integrated on the whole area orpart of the area on the outside of the plastic can body.
 3. The paintcan defined in claim 1, wherein the bottom edge of the internal moldedlabel can be extended to a position above the bottom of the plasticbottom frame with a height separation.
 4. The paint can defined in claim1, wherein the bottom edge of the internal molded label can be extendedto the bottom of the plastic bottom frame.
